[Resolved] PHP version of shortcodes with multiple parameters

Dear WP team,

In short: How to create a php snippet to display a WPSP list filtered with additional custom fields?

I’m using a shortcode to present a WPSP list but would ask for your help so it can be defined correctly via php instead. I’ve made a few attempts, without success.

The shortcode includes several additional parameters, related to a custom field created with the ACF plugin to rank & order the posts. Since i need to filter and order the output in a specific way, i adjusted the shortcode as suggested by Tom here.

The end result: [wp_show_posts id="1477" settings="meta_key=network-order&orderby=meta_value_num&order=ASC"]
– where “1477 is my list’s Id and “network-order” is the custom-field’s name

This works well but leads to a known problem: every time the page is edited anew, the “&” is replaced by “&”, breaking the functionality unless it’s manually cleaned. This has been (raised in another post, but the php equivalent was not indicated.

Since this is for a client, the manual editing step might fail and i would prefer to implement a php snippet to go in the functions.php of the child theme (based on Generate Press Pro, if relevant). The shortcode goes inside a container block (Generate Blocks, if relevant – i think you can spot a trend in user preferences here ;))

If doable, how should the php snippet look like?

Thank you in advance for your assistance!
Best,
Paulo
